IndraControl S20 Module With Safe Digital Outputs S20-SSDO-8/3
Observe all specifications in this manual and other applicable documents, re‐
fer to chapter 2.7 "Documentation" on page
Personal and property protection can only be ensured if the module is used
as intended, refer to chapter 2.6 "Intended use" on page
Depending on the wiring and the parameterization, the module detects errors
in the safety-related installations.
Repairs or user-specific changes at the module are prohibited. The housing
must not be opened. The module is protected against manipulations using
protective labels. In case of unauthorized repair or opening of the housing,
the protective label is damaged. The function of the safety module is not
guaranteed anymore in this case.
In case of error, send the module to Bosch Rexroth or contact the Bosch
Rexroth service immediately.
Ensure that the connections are neither interchanged, polarity is not reversed
nor manipulated. To better impede interchanging, plugs and slot markings
are colored.
WARNING
● Observe the notes on electric safety.
● Design the module used and perform their installation in the system ac‐
cording to the specific requirements.
● Check the systems upgraded with Csos again.
Ensure that all components connected to the system are protected against di‐
rect and indirect touching acc. to VDE 0100 part 410. If an error occurs, no
hazardous parasitic voltages may occur (single-failure proof!)
Required actions:
● Use power supply units with protective separation (PELV)
● Decoupling circuits, which are no PELV systems, via opto-couplers, re‐
lays and other components meeting the requirements on the safe sepa‐
ration.
Only use power supply units with protective separation and PELV voltage ac‐
cording to EN 50178/VDE 0160 (PELV). These power supply units exclude
short circuits between the primary and the secondary side.
Ensure that the output voltage of the voltage supply does also not exceed 32
V in case of error.
Observe the dirt and overvoltages at runtime when selecting equipment.
The module is designed for overvoltage category II (acc. to DIN EN 60664-1).
If overvoltages exceeding the values (defined in overvoltage category II) are
expected in the system, take additional measures to limit the voltage.
The machine or system vendor as well as the operator are reliable for the
safety of machine or system and the application used in the machine or sys‐
tem.
